    If you got any prints with that, you must be a genius!

    Praise the Lord ....

    And pass the electronic parts. Now to the web to find replacement porcelain sockets.

    Yep, Nicholas, it's a 12v deal, all else looks good, Thanks!

    I used it in the last four printing sessions, before I went mad....mad, frothing at the mouth, mad I tell you Steve!

    Jo,I hope you have success in your search but if not then you might try cleaning the two prongs on the bulb and the inside of the porcelain holder( the female end) can be cleaned with a small jeweller's round file or in the last resort with some wire-wool wrapped around a thick sewing needle. Well it worked in my Durst 605.

    The female socket is broken and one of the two contacts is burned away (I presume from arcing). I've got it rigged with make-do connectors fashioned from copper butt splices until I can come up with a replacement. One of my bulb suppliers has porcelain sockets; I've got an inquery in for the part # appropriate for the proper bulb. Big thanks!

    This talk about the socket sparked off my memory. I just checked the documentation for the colour-head (which uses 100w halogen bulbs) and it states the the socket is to be changed with every third bulb. Now I know why !

    I suppose the socket change is necessary because of the high working-temperature and the high current associated with halogen bulbs.

    Now THAT's good to know!

    I'll order a few! I don't have a manual for the enlarger, so Thanks, Martin!
